There are a lot of ways to strand a conductor (c.f. ASTM B 354). The common ones
are called unilay, concentric lay, semi-concentriclay, rope-lay and bunched (this is
avoided most of the time due to its irregular surface).
這句話的意思是:
導(dǎo)體有許多的絞合。通常有單層絞,同心層絞,不規(guī)則同心層絞,扭絞式絞和束絞幾種(束絞大多數(shù)是為避免導(dǎo)體表面不規(guī)則而采用的方法)
